Sand Forensics in Jamaica

Michael needs to prove that the white sand grains they saw from the helicopter and snuck off with came from his beach. He hires sedimentologists and marine geologists to run forensics on these tiny white sand grains. But it gets complicated because these hotels are raking the sand in the middle of the night. Resort hotels also yank out the grass from the bottom of the ocean so luxury resort feet don't get grazed by sea grass.
